To @ZZ whom t may concern:

Be it known that w e,.FnANir S'roNnR and CHARLES H, W. AirirnN, citizens of the United States and GreatBritain, respectively, residing at Corregidor Island and Manila, respectively, in the Philippine islands, have invented new and useful lmprovementsin internal-Combustion Motors, of which the following is a specification.

rIhis invention relates to internal combustion engines and has particular `relation to the valve mechanism of such engines, the primary object being the reduction of the number of valiesemployedfor the intake andexhaust ports, so as to reduce the working parts to a, minimum land ltoI accordingly reduce frictionv Vand eliminate thereby the consequent loss of power.

Another object Tof, the invention is .the

provision'of anovel form of valve, whereby asinglevalve lmay bel employed to control boththe intake and exhaustv ports. y

Another object isv the provision of a valve ofthe rotary type, Vwhich eliminates the ne-` cessity for springSt-he valve being operated .directlyfrom the engine crank shaft .and

rotated to its different positions, so that lproper .opening and closing of the intake and exhaust, ports is assured.

A further Objectis the provision of a fuel controlled valve, which is especially applicable for use in connection `with the first mentioned valve, wherebythe direction of flow of the fuel may be controlled to control the direction of travel of the engine.A

AV further object is the provision of an engine` of the above character, which is exceedingly simple inconstruction. and positive and efficient in operation. p

Other objects and advantages of the yinvention will appear asthefollowing description is read in connection with the accompanying drawings.

Referring'to tliedrawings in detail, there,

is illustrated a two cylinder engine ofthe four cycle type,l the, cylinders beinp` indicated at l5 y l y 'Y in these cylinders and haveftheir rodsgconnected to cranks 18vo`f ay shaftlQ, 4the latter operating within the bearings in thecrank case, vas will "be ,readily understood,` fThe positions of the cranks :18 ydiffer from the usual type of engine, in that yboth cranks are in alignmennor extend injthejsaine ,die rection, the purpose being to reciprocate the pistons inthe same direction'simultaneously, instead of operating'alternately, as is usual in explosive engines. i

Housed vwithin the engine casting, is' a,

valve chamber or cage 20, which is of cylinm 'dricalformation.,l and is provided withports 2l and 22,.which kcommun,icate with ports 23 and 24, respectivelylwhich in turn communicatewith the interior ,of Ithe cylinders 15 and 16.' The valve chamber'or cage 20 furthery provided with "ports 25 `which are located substantiall .o osite the orts 21 and 22. y pp p Mounted for rotation within the chamber..

and 1.6. Pistons lvvoperate withico ` notch 36.

so as to alternately open and close communication with the interior oit the cylinders 15 and 16 through the ports 23 and 24. The valve 20 is formed at one end with a socket 32, which is adapted to surround a vertical disposed shaft 33, the latter being mounted "for rotation in suitable hearings provided in the engine casting and surrounded by a packing gland to prevent leakage trom the valve chamber 20. rEhe socket has extending there across a diametrically disposed pin 35, which is seated in a notch 36, formed in the end ot the shaft 33 and provides al slipping connection between the shalt and valve. lt is, theretore, impossible to incorrectly place the valve, it being` only necessary to place the pin within the slot or Located within the valve charnber and bearing upon the valve are two pressure plates 3T, which act to take up any wear due to the operation oia the valve. rFliese plates are adjustable through the meY dium ot bolts 3TL and nut locks 38, so that proper pressure may be placed upon Ahe valve to insure its proper operation. Y

Secured upon the opposite end oit the shaft 33, is a worm 39, which is en gaged and driven by a worin 40, mounted upon the crank shaft. The gear 39 is preterably provided with twenty teeth and the worm 4() with live teeth, so that a ratio ot one to four ,is provided, the crank shatt making` tour complete revolutions to two coniplete revolutions oi' the valve 26.

Communicating with the interior oli the valve 26, are passages 41 and 42, the said passages being in communication with an intake manifold 43, through the medium oi passages 44 and respectively. These passages 44 and 45 are controlled by a valve 46` which will be hereinafter reierred to as the reversing valve. rlhis valve is also of hollow cylindrical shape and rotates within the chamber 47 which communicates with the passages 44 and 45. The reversing valve 46 is provided with a central passage 48, upon each side oitv which are located chambers 49 for communication with the atmose phere through the medium ot an outlet 50. Extending :trom the intake manifold 43, is a suitable connection 51, to which may be connected a carbureter (not shown) ot any suitable type. Thel passage 48 in the rcversing valve 46 is adapted to be moved into communication with either ol' the passages 44 or 45, by means olf a hand operated lever 52. rThe reversing valve 46 is turther provided with ports 53,v located upon opposite sides ot the passage 48, and as shown in Figure 2, when the last mentioned passage is in communication with the passage one of the ports 53 will be in passage with the other port 45.

ln the operation oi the engine, the cylinders lire alternately, as is usual in internal combustion engines, the operation being as follows: das is ted from the carburetor through the passage 48 of the reversing valve and through. the valve 26 to the cylinders ot the engine. Both pistons nieve downward and upward simultaneously, while the exn plosions occur alternately, both being at the limit otl the inner stroke starting upward. rl`hev valve 26 will then be in the position shown in Figure 5, cylinder 15 exhausting through 23, 21, 27, 45, 53 and 5() to vthe atmosphere. Cylinder 2 then starts on the compression stroke with the valve 26 covering port 22, which leads through the port 24 to cylinder 16. lVhen thep istons arrive at thc limit ot the outer stroke, cylinder 15 has entirely exhausted the exploded and cylinder 16 has reached lull compression and is ready :tor firing. When this occurs the valve 26 is in the position shown in Figure 6. Alter tiring the pistons start down ward and cylinder 15 sucks in the fr sh charge ot tuel through the carburetor, the passage 48 of the reversing valve 46, the passage 44 et the'intake manifold 43, the port 30, the port 21 and the port 23 to cylinder 15. Then the pistons again reach the inner limit ot' the stroke, the valve 26 is in the position shown in Figure 7. rEhe pistons again move upward or outward with the ports 21 and 23 closed to cylinder 15. During this upward movement the cylinder 16 will exhaust through the ports 24, 22, 2T, 42, 53 and 50 to the atmosphere. When the piston again arrives at the limit et the outer stroke, the valve 26 is in the position shown in Figure'8, cylinder 15 being again ready to lire. lhen this occurs the pistons move downward and cylinder 16 takes in a liresh charge through the ports 48, 44, 30, 22 and 24. rlfhis completes the 'tour strokes of the cycle ot the operation, the crank shalt having made two complete revolutions, while the valve 26 has made only one.

To reverse the direction ot operation of the engine, the lever 52 is operated to rotate the reversing valve, so that the passage 48 will communicate with the passage 45, and one of the ports with the passage 43. rThe fuel exhaust gases will then enter and leave the cylinders in an opposite direction from that above explained, so that a reverse motion of the engine is obtained. As the explosions occur in one or other ot the cylinders the exhaust always takes place at the end oit the inner'or bottom stroke ot the pistons through the ports 60 provided in each oit the engine cylinders. rl`his reduces the charge in the cylinders to atmospheric pressure and leaves only the burnt charge to be expelled through valve 2() to the atmosphere and thereby entirely empties the cylinders, leaving them ready tor a full charge of fresh fuel.

The invention is susceptible ot various 1. rlfhel combination With a multiple cyl`r inder engine having spaced fuel passagesl and means for alternately opening and closingl said passages at one end thereof, of a valve chamber arranged at the oppositev end of the spaced fuel passages and in communication therewith, said fuel passages enter-v ing the chamber from the same side, a hollow cylindrical reversing valve mounted for rotation in said chamber and provided With a centrally disposed passage, one end of which is adapted to be registered with either of the spaced fuel passages,vv7hile the op` posite end is in constant communication With the intake mani-fold ofthe engine, a pair of chambers D-shaped in cross section, one of which is arranged on each side of the centrally disposed passa-ge7 said chambers are provided With ports alternately registering with either ofthe spaced `fuel passages When the centrally disposed passage is in communication with the other spaced fuel passageand` a manually operated `lever for rotating the valve for changing 4the action of the engine.
